For example, for small interest rate changes, the duration is the approximate percentage by which the value of the bond will fall for a 1% per annum increase in market interest rate. So the market price of a 17-year bond with a duration of 7 would fall about 7% if the market interest rate (or more precisely the corresponding force of interest ...
The bonds are purchased from the market at $985.50. Given that $2.00 pays the accrued interest, the remainder ($983.50) represents the underlying value of the bonds. The following table illustrates the values of these terms. The market convention for corporate bond prices assigns a quoted (clean price) of $983.50.
Pull to Par is the effect in which the price of a bond converges to par value as time passes. At maturity the price of a debt instrument in good standing should equal its par (or face value). [1] Another name for this effect is reduction of maturity. It results from the difference between market interest rate and the nominal yield on the bond.
An important part of the bond market is the government bond market, because of its size and liquidity. Government bonds are often used to compare other bonds to measure credit risk . Because of the inverse relationship between bond valuation and interest rates (or yields), the bond market is often used to indicate changes in interest rates or ...
Interest payments are the primary way bonds generate returns for investors.
Analytic Example: Given: 0.5-year spot rate, Z1 = 4%, and 1-year spot rate, Z2 = 4.3% (we can get these rates from T-Bills which are zero-coupon); and the par rate on a 1.5-year semi-annual coupon bond, R3 = 4.5%. We then use these rates to calculate the 1.5 year spot rate. We solve the 1.5 year spot rate, Z3, by the formula below:
The Z-spread of a bond is the number of basis points (bp, or 0.01%) that one needs to add to the Treasury yield curve (or technically to Treasury forward rates) so that the Net present value of the bond cash flows (using the adjusted yield curve) equals the market price of the bond (including accrued interest). The spread is calculated iteratively.
Finance scholar Frank J. Fabozzi has stated that because of the coupon effect, a yield-to-maturity yield curve should not be used to value bonds. [3] Par yield analysis is useful because it avoids the coupon effect, since a bond trading at par has a coupon yield equal to its yield to maturity, according to Martinelli et al. [ 4 ]
